一 前言 在现代科学研究中,实验技术是其最活跃的重要方面。现代科学研究首要的问题是根据实验结果(而不是根据猜测)建立研究对象的物理模型,然后再进行研究分析。流体力学研究中的流场显示技术,其任务就是把存在于透明介质(空气、水……等)中的流动现象,(其中很多现象是直接看不见的。)不仅设法用图像显示出来,并力求做到根据这些图像作流场某些物理量的定量测定。
I. INTRODUCTION In modern scientific research, experimental technology is one of the most active and important aspects. The primary problem of modern scientific research is to establish a physical model of the subject based on experimental results, rather than on speculation, and then conduct research and analysis. Flow-field display techniques in fluid mechanics research whose task is to move the flow phenomena that exist in transparent media (air, water, etc.), many of which are not directly visible, not only try to visualize them Strive to do according to these images for the flow field quantitative determination of some physical quantities.
